==============================================================================
INTRODUCTION *deoplete-introduction*
*deoplete* is the abbreviation of "dark powered neo-completion". It
provides asynchronous keyword completion system in the
current buffer.
Note: deoplete may consume more memory than other plugins do.
Improvements in deoplete in comparison to |neocomplete|:
1. Real asynchronous completion behavior like |YouCompleteMe| by default.
2. Uses Python3 to implement sources.
3. Removes legacy interface.
4. Requires |+python3|.
==============================================================================
INSTALL *deoplete-install*
Note: deoplete requires Neovim (0.2.0+) or Vim8 (latest is recommended) with
Python3.5+ and |+timers| enabled.
Please install nvim-yarp plugin for Vim8.
https://github.com/roxma/nvim-yarp
Please install vim-hug-neovim-rpc plugin for Vim8.
https://github.com/roxma/vim-hug-neovim-rpc
1. Extract the files and put them in your Neovim or .vim directory
(usually `$XDG_CONFIG_HOME/nvim/`).
2. Call |deoplete#enable()| or set "let g:deoplete#enable_at_startup = 1" in
your `init.vim`/`vimrc`
3. Execute the ":UpdateRemotePlugins" if Neovim.
If ":echo has('python3')" returns `1`, then you're done; otherwise, see below.
You can enable Python3 interface with pip: >
pip3 install neovim
Note: deoplete needs neovim-python ver.0.2.4+.
You need update neovim-python module.
>
pip3 install --upgrade neovim
<
If you want to read for Neovim-python/python3 interface install documentation,
you should read |provider-python| and the Wiki.
https://github.com/zchee/deoplete-jedi/wiki/Setting-up-Python-for-Neovim
You can check the Python3 installation by using the |:checkhealth| command.
==============================================================================
INTERFACE *deoplete-interface*
------------------------------------------------------------------------------
OPTIONS *deoplete-options*
Options can be toggled through the use of |deoplete#custom#option()|.
For example:
>
" Set a single option
call deoplete#custom#option('auto_complete_delay', 200)
" Pass a dictionary to set multiple options
call deoplete#custom#option({
\ 'auto_complete_delay': 200,
\ 'smart_case': v:true,
\ })
<
The set of available options follows.
*deoplete-options-async_timeout*
async_timeout
The timeout of asynchronous completion.
Default: 150
*deoplete-options-auto_complete*
auto_complete
If it is False, automatic completion becomes invalid, but can
use the manual completion by |deoplete#manual_complete()|.
Default: v:true
*deoplete-options-auto_complete_delay*
auto_complete_delay
Delay the completion after input in milliseconds.
Default value: 20
*deoplete-options-auto_refresh_delay*
auto_refresh_delay
Delay the refresh when asynchronous.
If it is less than equal 0, the feature is disabled.
Default value: 50
*deoplete-options-camel_case*
camel_case
If it is True, lowercase letters are also matched with the
corresponding uppercase ones.
Ex: "foB" is matched with "FooBar" but not with "foobar".
Note: This feature is only available in
|deoplete-filter-matcher_fuzzy| or
|deoplete-filter-matcher_full_fuzzy|.
Default value: v:false
*deoplete-options-complete_method*
complete_method
If it is "complete", deoplete use |complete()|.
If it is "completefunc", deoplete use |i_CTRL-X_CTRL-U|.
Note: It changes current 'completefunc' value.
If it is "omnifunc", deoplete use |i_CTRL-X_CTRL-O|.
Note: It changes current 'omnifunc' value.
Default value: "complete"
*deoplete-options-delimiters*
delimiters
Delimiters list. It is used in
|deoplete-filter-converter_auto_delimiter|.
Default value: ['/']
*deoplete-options-ignore_case*
ignore_case
If it is True, deoplete ignores case.
Default value: same with your 'ignorecase' value
*deoplete-options-ignore_sources*
ignore_sources
It is a dictionary to decide ignore source names.
The key is filetype and the value is source names list.
Default value: {}
*deoplete-options-keyword_patterns*
keyword_patterns
It defines the keyword patterns for completion.
This is appointed in regular expression string or list every
file type.
Note: It is Python3 regexp. But "\k" is converted to
'iskeyword' pattern.
>
call deoplete#custom#option('keyword_patterns', {
\ '_': '[a-zA-Z_]\k*',
\ 'tex': '\\?[a-zA-Z_]\w*',
\ 'ruby': '[a-zA-Z_]\w*[!?]?',
\})
<
Default value: {}
*deoplete-options-max_list*
max_list
Show up to this limit candidates.
Default value: 500
*deoplete-options-num_processes*
num_processes
The number of processes used for the deoplete parallel
feature.
If it is 1, this feature is disabled.
If it is less than or equal to 0, the number of processes is
equal to that of sources.
Default value: 1 (Windows) or 4 (Others)
*deoplete-options-omni_patterns*
omni_patterns
If omni_patterns is set, deoplete will call 'omnifunc'
directly as soon as a pattern is matched.
Note: This will disable deoplete filtering and combination of
sources for those matches. Suggested use is only for legacy
omnifunc plugins which do not return all results when provided
an empty base argument or moves the cursor in omnifunc. See
|complete-functions|
If this pattern is not defined or empty for a filetype,
deoplete does not call 'omnifunc'.
Note: It is a Vim regexp.
>
call deoplete#custom#option('omni_patterns', {
\ 'java': '[^. *\t]\.\w*',
\})
<
Default value: in autoload/deoplete/init.vim
*deoplete-options-on_insert_enter*
on_insert_enter
Deoplete enables the auto completion on |InsertEnter| autocmd
if this value is True.
Default value: v:true
*deoplete-options-on_text_changed_i*
on_text_changed_i
Deoplete enables the auto completion on |TextChangedI| autocmd
if this value is True.
Default value: v:true
*deoplete-options-profile*
profile
If it is True, deoplete will print the time information to
|deoplete#enable_logging()| logfile.
Must be set in init.vim/vimrc before starting Neovim/Vim.
Does not support command line.
Default value: v:false

SOURCES *deoplete-sources*
around *deoplete-source-around*
This source collects candidates around the cursor, namely
inside current buffer. Plus, it searches keywords in
|:changes| command output. Therefore, this source provides
the words that are in sight or the ones you've just typed
somewhere else.
Legend: You can see where the words came from. Next to the
source mark [~] these suffixes are used:
A - above the cursor
B - below the cursor
C - in changes
rank: 300
buffer *deoplete-source-buffer*
This source collects keywords from current buffer and the
current tabpage windows buffers and the opened buffers which
have same 'filetype'.
Note: It does not collect keywords from not loaded buffer.
For example, if you open file by "nvim A B". A is already
loaded, but B is not loaded. So buffer source cannot collect
the keywords in B until you switch to buffer B.
Note: It takes time to get the candidates in the first time if
you want to edit the large files (like Vim 22000 lines eval.c).
rank: 100
Source custom variables:
require_same_filetype
If it is False, deoplete collects keywords from
buffers of any filetype
(default: True)
dictionary *deoplete-source-dictionary*
This source collects |deoplete-options-keyword_patterns|
keywords from 'dictionary'.
Note: It uses buffer-local 'dictionary' set up.
Note: It also supports directory.
rank: 100

" Examples:
" Sample configuration for dictionary source with multiple
" dictionary files.
setlocal dictionary+=/usr/share/dict/words

file *deoplete-source-file*
This source collects keywords from local files. Specifically,
it completes file and directory names and paths, e.g.
/usr/lib/share.
rank: 150
Source custom variables:
enable_buffer_path
If it is True, file source completes the files
from the buffer path instead of the current
directory.

contain "/".
If it is less than 0, it is disabled.
(default: -1)
member *deoplete-source-member*
This source collects members from current buffer.
rank: 100
Source custom variables:
prefix_patterns
This dictionary records prefix patterns to
member completion. This is appointed in
regular expression string or list every file
type. If this pattern is not defined or
empty, deoplete does not complete member
candidates.
Note: It is Python3 regexp.
(default: See in member.py)
omni *deoplete-source-omni*
This source collects keywords from 'omnifunc'.
Note: It is not asynchronous.
rank: 500
Source custom variables:
functions
It defines a dictionary for omni completion
with deoplete:
- `keys` consist of filetypes;
- `values` consist of either a string
containing a single omnifunc or a list with
omnifuncs to be used for each filetype.
In case there is no omnifunc setting for the
current filetype in the dictionary, deoplete
will use the 'omnifunc' setting.
Note: It supports context filetype feature
instead of 'omnifunc'. You can call the
omnifunc in the embedded language.
Note: For omnifunctions to work with deoplete,
it's necessary to setup the "input_patterns"
setting.
(default: {})
>
call deoplete#custom#source('omni', 'functions', {
\ 'ruby': 'rubycomplete#Complete',
\ 'javascript': ['tern#Complete', 'jspc#omni']
\})
<
input_patterns
This dictionary records keyword patterns to
Omni completion. This is appointed in regular
expression string or list every file type. If
this pattern is not defined or empty, deoplete
does not call 'omnifunc'.
Note: Some omnifuncs which moves the cursor is
not worked. For example, htmlcomplete,
phpcomplete, etc...
Note: It is Python3 regexp.
